  • The box contains 100 pieces, which may be more than needed for shooters who only load in small batches.
  • It is specific to .243 Winchester, so it is only suitable for that cartridge and not a general-purpose brass option.
  • The product description emphasizes quality control and testing, but it does not provide load data or performance details for finished ammunition.
